The operation of the dies is as follows The end of the fuse material isled from the 'reel 3 through the hole 2L in the lower cut" ting andsplitting. die, passed round the *guide spool 4 and led to the crimpingdies.

A cap is slipped" over the end oft-he length of fuse and the cappositioned between the crimping dies. The pedal 18 is then de-. pressed;causing asimultaneousoperation of bothsets'of dies. The cuttingandsplitting dies cut oif a length of-fuse and split the endadjacentythe cut. The crimping dies ,cirimpflthe capon the. other endofthe fuse;

as 'shownin Fig. 8. ,The length'ofthe fuse, it will be seen has been]determined by the position of the guide spool. Another length of thefuse material is then drawn from the cutting and splitting device roundthe'guidc spool to thecrimping dies and the operation -of cutting,splitting and crimping repeated.
